NOZZLE CONNECTION FOR LARGE-SIZED SUCTION HOSE.

Application filed August 24, 1925. Serial No 52,177. i

This I invention relates to an improved nozzle connection for large sized suction hose. e

The objects of the invention are:

First, to provide such a nozzle which Wlll connect with round or square apertures such as a furnace door or a pipe opening into a furnace casing, and which will connect readily with my improved pipe which I have described in a companion application.

'Second, to provide such a coupling which is exceedingly flexible and adjustable as to size and shape and also one which is very durable and economical to manufacture.

Objects pertaining to details and economies of my invention will clearly appear from the detailed description to follow.

I accomplish the objects of my invention by the devices and means described in the following specification. The invention is clearly defined and pointed out in the claims.

A structure embodying the features of my invention is clearly illustrated in the accompanying drawing forming a part of this application, in which:

Fig. 1 is a. side elevation view of my improved nozzle.

Fig. 2 is an enlarged detail longitudinal sectional view showing the nozzle inserted into a furnace door. taken on line 22 of Figs. 1 and 3. 1

Fig. 3 is a detail perspective View showing the nozzle as it is inserted into the door frame of a furnace.

Fig. l is an enlarged detail view partially in section on line 4-4 of Figs. 1 and 2.

Fig. 5 is a detail perspective view of the nozzle with the outer fabric case removed except as to one corner showing details of construction.

In the drawing the sectional views ar taken looking in the direction of the little arrows at the ends of the section lines and similar numerals of-reference indicate similar parts in all the views.

The parts of my improved nozzle structure will be identified by their numerals of reference. '1 is the outer fabric shell or casing. 2 is the main supporting or carrying ring at the inner end of the nozzle. The fabric is rolled upon itself at 11 and secured to this main ring 2 by rivets 22 after the manner of construction of my pipe aforesaid.

Longitudinal. flat blade spring fingers 3 are secured b the rivets 22 to this supporting ring 2 and extend with their outer ends free except for a flexible fabric support.--

The outer end of the nozzle is made up of a reinforced fabric supporting ring 12 which is folded upon itself at 13 on the outside to form a. cushion for the flexible connection and packing of the outer end of the nozzle, and is rolled upon itself at 14 on the inside to give strength and support to the outer ends of the springs 3.

These springs 3 are distended and forced outwardly by the expansionring 4 which is seen that while the normal shape of the outer end of the nozzle is round, owing to the fact that there is a flexible connection between the outer ends of the springs 3, it is possible toconform the nozzle to square or other shapes, and to collapse the same into a considerable range of size openings. It can be readily inserted into the fire door of a furnace, or it can be inserted into the end of the cold air pipe, or into a suitable aperture cut in the casing where it is very quick ly applied and effective in use.

Ofcourse, any small leaks about the nozzle may be stopped by a suitable wrapping of any material which will be drawn and held into place by the suction.

Ihave described my improved nozzle in its preferred form. .It can, of course, be considerably varied inits details without departing from my invention. 'Ihe'particular way in which I dilate thesprings is very effective but they might be effectively supported on a broad ring, and, in fact, they need ver 'little support for any purpose. Therefore, I desire to claim the supporting ring specifically, and also to claim the structure without that device. As indicated, I wish to claim, the invention broadly as well as specifically as pointed out in the appended claims.

Having thus described my invention what I claim as new and desire to secure by Letshell, a main supporting ring at its inner end suitably flanged inwardly, the fabric being rolled upon itself to form an outer packing member in connection therewith, a series of longitudinal supporting springs riveted to the said main ring with their outer ends free except for the support of the fabric shell, a flexible support member rolled upon itself within the outer end of the nozzle and outwardly over the outer ends of the said flexible supporting springs and suitably riveted to the ends of said springs, and a dilating ring disposed within the said nozzle and retained in position by hooks over the same and over the main ring, all coacting substantially as described for the purpose specified.

2. A nozzle comprising an outer fabric shell, a main supporting ring at its inner end suitably flanged inwardlly, the fabric being rolled upon itself to form an outer packing member in connection therewith, a series of longitudinal supporting springs riveted to the said main ring with their outer ends free except for the support of the fabric shell, and a flexible support member rolled upon itself within the outer end of the nozzle and outwardly over the outer ends of the said flexible supporting springs and suitably riveted to the ends of said springs, all coacting substantially as described for the purpose specified.

3. A nozzle comprising an outer fabric shell, a main supporting ring at its inner end suitably flanged inwardly, the fabric being rolled upon itself to form an outer packing member in connection therewith, a series of longitudinal supporting springs riveted to the said main ring with their outer ends free except for the support of the fabric shell, and a dilating ring disposed within the said nozzle and retained in position by hooks over the same and over the main ring, all coacting substantially as d scribed for the purpose specified.

4. A nozzle comprising an outer fabric shell, a main supporting ring at its inner end suitably flanged inwardly, the fabric being rolle upon itself to form an outer packing member in connection therewith, and aseries of longitudinal supporting springs riveted to the said main ring with their outer ends free except for the support of the fabric shell, all coacting substantial- 1y as described for the purpose specified.

5. A nozzle comprising an outer fabric shell, a main supporting ring, longitudinal springs secured to the ring and retained with their free ends secured within the fabric easing. and a dilating ring for the said springs, coacting as specified.

6. A nozzle comprising an outer fabric shell, :1 main supporting ring, and longitudinal springs secured to the ring and retained with their free ends secured within the fabric easing, coacting as specified.

In witness whereof I have hereunto set my hand.

TITUS RUSSELL.
